T1-Irrigated control, T2-Untreated plants grown under rainfed conditions, T3-Coinouclation of P. chinense and B. cereus, T4-Consortium of PGPR and SA, T5-SA only. Different letter shows that the difference is statistically significant (P < 0.05) within treatments and ± represents standard error values.
